where single reverse-bars are fitted below inner bottom to be 
joggled over outer frame-bar to take one rivet. Between these 
outer and reverse-bars bracket-plates 12J pounds per square 
foot next the vertical keel, and 10 pounds per square foot 
elsewhere, will be worked as shown on the midship-section, to 
be connected to the vertical keel and longitudinals by angle- 
bars 2J x 2 j- inches of 5 pounds per foot. In wake of the 
engines, boiler-saddles, and elsewhere, as may be necessary, 
special frames are to be introduced, and solid plates lightened 
with holes substituted for the bracket-plates, as required. 

The solid or water-tight frames are to be made of plates 10

A bracket or floor-plate 10 pounds per square foot is to be 
worked to form the lower part of the frame, the Z-bar will 
be split up at lower end and opened out, the lower part form¬ 
ing the ordinary outer frame angle-bar to butt against the 
vertical keel, the upper part forming the reverse-bar, and to 
extend about 2J- feet past the middle line and button alternate 
sides, the butts to be covered by suitable straps; the plates 
to be well riveted to the outer and reverse-bars and con¬

Where the sides of the vessel are recessed above the gun- 
deck forward and abaft the gun-sponsons nearest the extremi¬ 
ties of the vessel, the frames will cut off at 7 inches above 
the gun-deck stringer-plate; above this plate the frames will 
be made of Z-bars, same dimensions and weight as the frames 
below, to be split at the lower end, and the outer part forming 
the ordinary outer angle-bar opened out to the required curve 
or shape, as shown on the cross-sections, the inner part form¬ 
ing the reverse-bar to continue down straight to the stringer- 
plate; between these bars a plate 10 pounds per square foot 
will be riveted, to be lightened with holes as indicated on 



9 


plans; angle-bars 2\ x 24 inches of 5 pounds per foot to be 
worked to connect these frames to gun-deck stringer-plate and 
beams. 

Between the berth and gun-decks, on frames 22 and 58, 
belt-frames 12J pounds per square foot will be worked, to be 
connected to the outside plating by angle-bar 3x3 inches of 
7 pounds per foot, stiffened on the inner edge by double angle- 
bars 2J x 2J inches of 5 pounds per foot, to be well riveted to 
the gun-deck beams and connected to the berth-deck plating 
by angle-bars 3J x 3 inches of 8 pounds per foot. To be 
worked in shape and size, also lightened with holes, as shown 
on the midship section. 

All transverse frames to be continued up to the height indi¬ 
cated on the profile and section plans. 

Special framing to be worked at the intersection of the top¬ 
side and gun-sponsons, also in wake of shaft-bearers and struts 
and other important parts requiring special strengthening. 

At the extremities of the vessel the frames will be worked 
as indicated on plans of stern-post and stem.

ehain-riveted, the straps to be single, and of the same thick¬ 
ness as the plates, and their length to be 11J times the diam¬ 
eter of the rivets. The butts of the inner angle-bar to be 
midway between the lines of rivets in the frames, and not in 
the same space with the lightening-hole or the butt of the 
adjacent plates, the covering-angles to them in this case being 
dispensed with. 

Before and Abaft the Double Bottom: The 1st longitudinal 
from the keel on each side will be formed of intercostal plates 
15 pounds per square foot, to extend from frame 14 to about 
frame 86, to be connected to the floor-plates by angle-bars 
2J x 2 \ inches of 5 pounds per foot, and on lower edge to 
the outside plating by 3 x 3 inches of 7 pounds per foot 
angle-bars between the frames; on upper edge to be connected 
by intercostal angles 3x3 inches of 7 pounds per foot to the 
inner bottom, the inner angles forward of frame 16 to be con¬ 
nected over the reverse-bars by lozenge-shaped straps 12J 
pounds per square foot, well riveted to angles and frame-bars.

structed similarly to the 1st longitudinal, except that forward 
of frame 31 a Z-bar 5 x 3 x 2^ inches of 12 pounds per foot 
will be worked on the upper edge, well riveted to the plates, 
which will be made of sufficient depth to admit of this being 
done, also riveted to the reverse flanges of the frames; and, 
in order'to preserve the continuity of longitudinal strength of 
the vessel, the fore-part of this 2d longitudinal will be grad¬ 
ually twisted so as to make good connection with the after-end 
of horizontal flat abaft of, and connecting with, ram-plate. 
Abaft the after-end of tapered plate of inner bottom at frame 
75 there will be secured to the intercostal angles on upper 
edge of longitudinal a flat plate 12 inches wide and 12J 
pounds per square foot, well riveted to the reverse-flanges of

worked in the longest lengths practicable, the butts to be 
properly shifted and suitably strapped and double-riveted; 
the plates to be generally worked in lengths of five frame 
spaces within the double bottom, or longer if necessary to give 
good shift of butts. 

Within the double bottom the plates of the 1st and 2d longi¬ 
tudinals from the keel to be lighted with holes, which are to 
be arranged with a view to the freedom of access required 
within the compartments of the double bottom and with 
reference to the butts in the adjacent plating, taking care to 
preserve uniformity of strength in the several frame-spaces. 

Openings are to be left in the upper edge of the 1st and 2d 
longitudinals from the keel where required in each compart¬ 
ment, to allow air to escape when filling the double bottom.

at least 24 hours, possess an insulation of not less than 1,000 
megohms per nautical mile. It shall have a conducting area 
of not less than one square millimeter per every 1J amperes 
of current that may pass through it. It shall, when laid about 
the ship, be inclosed in securely fastened wooden molding, and 
the exterior of any two conductors shall be separated by some 
insulating substance at least \ of an inch. The molding shall

may be required, in order to fully light up all parts of the 
ship, including coal-bunkers, magazines, shell and ammuni¬ 
tion-rooms, running lights, and lights for use on the upper 
deck and aloft. They shall be arranged in sections not to 
exceed fourteen in number, so that complete control over each 



69 


section may be had by means of switches placed in the dynamo- 
room. Each lamp shall be supplied with a key-socket, or 
a keyless socket and a water-tight switch, as may be designated, 
and a spring to reduce the transmission of shocks. All metal 
parts oil lamps, sockets, and switches shall be nickel-plated.

the most approved form for ship use, and subject to selection. 

[ Insulation .—The dynamos, the exterior or outer coating of 
all conductors, all fixtures, junction of boxes and other parts 
of the system shall be insulated from the ship. All junction- 
boxes, switches, conductors, and joints of conductors shall be 
water-tight. When complete, with all connections made ready 
for the use of each and every lamp, the insulation of the sys¬ 
tem complete, including the dynamo, shall not be less than 
1,000 ohms of resistance to every volt of electromotive force 
of the dynamo. 

Spare parts .—Such spare parts of the engines, dynamos, 

• and other portions of the plant shall be provided as will 
enable it to be used for a period of three years without further 
supplies being received. The amount of such spare parts and 
supplies to be based upon the supposition that the plant will 
& receive good and intelligent care, that one engine and dynamo 
will always be in operation, and that each lamp will average 
in use three hours daily. 

ELECTRIC CALL-BELLS. 

Electric call-bells, with all necessary batteries, wires, but¬ 
tons, of the best and most substantial materials,’ to be fitted 
complete throughout the ship, as directed. 

HEELING SHIP.

SWINGING-TABLES AND BENCHES FOR CREW. 

To be made of white ash, with galvanized-iron fittings. 
These tables and benches are to have a capacity for about 300 
men, and to be fitted as is usual in the naval service, and 
I stowed between the beams in convenient manner, as directed. 

CLEANING, GALVANIZING, ETC. 

All steel and iron work is to be carefully scraped, scaled, 
and cleaned before being painted. The plates of the bottom, 
the lower plates of bulkheads, the floor-plates of frames, and 
other plates as may be directed, are to be treated as follows, 
lor the purpose of removing the black oxide or scale: The 
plates, before being taken in hand for working, are to be im¬ 
mersed for a few hours in a liquid consisting of 19 parts of 
water and one of hydrochloric acid. The plates should be 
pickled on edge and not laid flat. When the plates are re¬ 
moved from the dilute acid, both surfaces are to be well 
brushed and washed to remove any scale which may still ad- 
■ here to them. They should then be placed in another bath 
filled and kept well supplied with fresh water, and be 
thoroughly washed with a hose, as may be found necessary. 
The plates on removal from the fresh water should be placed 
on edge to dry. 

| The heels of all iron or steel awning-stanchions, guard-rail 
stanchions, and all gratings, eye and ring-bolts, coal-scuttle 
frames, lids, and gratings, rubbing-plates, armament fittings, 
Ac., and all fastenings for wood-ceiling in hold, store-rooms, 
Ac., the lower plates of all bulkheads in lower hold, and 
all such outfits exposed to the weather, to be thoroughly 
galvanized as may be directed. 

PAINTING AND OTHERWISE COATING STEEL, IRON, AND 
WOOD-WORK. 

The entire inside of vessel, except that portion on berth- 
deck not occupied by the machinery, boilers, and coal, and 
under poop and forecastle-decks, is to be covered with three 
good coats of the best oil-paint. 






71 


The inside of plating, the frames above berth and main- 
decks, the deck-beams, plating, ties, stringers overhead, bulk¬ 
heads on the berth-deck in wing-passage, the fire-room and 
engine-room hatch-casings, ward-room and all its adjacent 
rooms, are to First, receive a priming-coat of red lead; second, 
before the wood-work of any kind is put in place a coat of 
white lead mixed with a proper proportion of varnish or some 
other adhesive substance; third, before this coating is hard 
there is to be applied a coating of pulverized cork as thick as 
possible, the cork to be of such degree of fineness as may be 
directed; fourth, after the paint holding the cork is hard, 
two coats of best white-lead paint is to be applied over the 
cork and finished with a coat of white china-gloss. 

The object of this cork facing is to prevent radiation and 
condensation, aud care must be taken to have every part of 
metal thoroughly covered with the cork. 

The exterior of the vessel above water-line is to be covered 
with a good coat of cement equal to Tibbie’s, and finished with 
not less than two coats of black. When the vessel is delivered 
all paint-work inside and out must be clean and fresh. 

All deck-iron or steel work, including inside of hammock- 
nettings, outside of hatch-coamings, davits, anchor-gear, &c., 
to be cemented same as exterior of hull. 

All hard woods to be dead-finished with the very best mate¬ 
rials and in the best manner. All wood-work not polished 
to have three coats of the best white-lead paint and finished 
with white china-gloss. Where required the joints of wood¬ 
work will be put together with white lead. The bottom, from 
the water-line down, will be covered with the most approved 
anti-corrosive and anti-fouling material, as may be directed. 

CALKING. 

The whole of the calking in the vessel to be performed in 
the most satisfactory manner; if it should be considered neces¬ 
sary by the superintending constructor, before the vessel is 
delivered by the contractor to the Navy Department, to re-calk 
the decks, &c., and reconcile the edges, the same is to be done by 



72 


and at the expense of the contractor; and if any portion, or the 
whole of the calking should be found on final survey not to be 
done in such an efficient manner as required, the same is to be 
fre-calked and the expense thereof deducted from the contrac¬ 
tor’s final bill. 

The oakum is to be equal to that used by the Government 
in calking vessels of the U. S. Navy. 

CLEANING DIRT, CHIPS, ETC., FROM BILGES, COMPARTMENTS, 

ETC. 

All to be carefully cleaned out before the vessel is delivered 
by the contractor; also during the progress of the work, the 
chips, shavings, dirt, &c.,to be cleaned out daily, and particu¬ 
lar care must be taken that all foreign matter is removed and 
the parts thoroughly cleaned before the application of any 
paint or cement. 

GROUNDING. 

\ Great care is to be taken that the vessel does not at any 
time take ground ; should this occur, however, before the con¬ 
tract is completed, the vessel will be docked, thoroughly ex¬ 
amined, and all injury arising therefrom or from coming in 
contact with wharf or floating objects must be repaired to the 
entire satisfaction of the superintending constructor, and at 
the expense of the contractor. 

TESTING FORGED WORK. 

All shackles, ring and eye-bolts, stopper-bolts, eyes, hooks, 
slips or triggers, all blocks, anchor-davits, struts, chain-plates, 
and boat-davits, &c., are to be tested by strain or proved in 
satisfactory manner. On no account are jumped-welds to be 
made in important forgings. If any forgings or other iron or 
steel work should be sub-let by the contractor, the sub-con¬ 
tractor shall be informed by the contractor that such forgings 
are to be done under the immediate supervision of the superin¬ 
tending constructor. 






76 


All other plates and shapes may be accepted if the weights vary be¬ 
tween the specified weights and 5 per cent, below them. 

All plates and shapes not being within the limits here specified may 
be rejected. 

TESTS. 

All material except boiler-plates should be tested by heats, as follows: 

A specimen ingot or bloom shall be selected and rolled into a plate 
or bar and test pieces cut therefrom, provided, always, that the test 
pieces shall have received no more working than that which the finished 
material from the heat would receive. 

Fig. 1. 


A B 

_^-N_ 

Four test pieces, of the form shown in figure 1, for plates—a square 
or round, in condition as finished at the rolls, may be used for the 
tests of shapes—shall be made and tested for each heat. 

The length A B must be at least 8 inches of uniform cross-section 
of which the area should not be less than £ or more than -,- 8 0 - of one 
square inch. 

The reduction of the length A B should be just sufficient to prevent 
failure in the grip. 

The test pieces must not be annealed unless the finished material is 
to be annealed. 

Each test piece shall be submitted to a direct tensile stress until it 
breaks, and in a machine of approved character. 

The initial stress to be 30,000 pounds per square inch. 

The first load to be kept in continuous action for one minute. An 
observation to be made of the corresponding elongation measured 
upon the original length of 8 inches. 

The stress then to be increased slowly until the principal elastic 
limit is determined, after which additional loads will be added at in¬ 
tervals of time as nearly as possible equal, and separated by half a 
minute; the loads to produce an increase of stress of 5,000 pounds per 
square inch of original section of the test piece until the stress is 
about 50,000 pounds per square inch of original section, when the 










t 


77 


increments of stress should not exceed 1,000 pounds per square inch. 
Upon close approach to the probable ultimate strength, the load to be 
increased gradually and its maximum value carefully noted. 

The final elongation to be that obtained after rupture. 

A list of all ingots made from each heat must be supplied to the in¬ 
spector. Each ingot should be stamped in his presence with the number 
of the heat. He should also see the test plate or billet cut olf, stamped 
and rolled, and place a private stan ~ ^on it in such a way that each 
test piece will have the impression. the \aTnp near one end. 

CONDITIONS OF ACCEPTANCE. 

In order to be accepted the average of the four test pieces must show 
an ultimate tensile strength of at least 60,000 pounds per square inch 
of original section, and a final elongation in eight inches of not less 
than 23 per centum. 

Material which shows a strength greater than 60,000 pounds per 
square inch will be accepted, provided the ductility remains at least 
23 per centum. 

CASES OF FAILURE. 

If the average of these four test pieces, numbers 1, 2,3,4 (called 
Test I), fall below either of the required limits, the ingot from which 
pieces 1,2,3,4 were cut shall be rejected, and Test II made, consisting 
of pieces 5 and 6, cut from a second ingot; if the mean of the results 
of these two fall below either of the above limits, the entire lot shall 
be rejected. If it be successful, Test III, or the mean of pieces 7 and 
8, cut from a third ingot shall decide. 

If in any of the tests I, II, III, any single piece shows a tensile stress 
less than 58,000 pounds, or a final elongation less than 21 per cent., the 
ingot from which it was taken shall be rejected and that test consid¬ 
ered to havd failed, regardless of its average. 

QUENCHING TEST. 

IV.—A test piece shall be cut from each plate, angle, or beam, and 
after heating to a cherry-red plunged in water at a temperature of 
82° Fahrenheit. Thus prepared it must be possible to bend the pieces 
under a press or hammer so that they shall be doubled round a curve of 
which the diameter is not more than one and a half times the thick¬ 
ness of the plates tested without presenting any trace of cracking. 

These test pieces must not have their sheared sides rounded off, the 
only treatment permitted being taking off the sharpness of the edges 
with a fine file. Inspectors may require a cold bending test when con¬ 
sidered necessary.

73 


TESTING RED LEAD. 

The contractor is to provide crucibles, &c., for testing red 
lead, and all red lead is to be tested and proved satisfactory by 
the superintending constructor before being used. 

TESTING WATER-TIGHT COMPARTMENTS, TANKS, ETC. 

All water-tight compartments are to be tested by filling the 
compartments with water as may be directed, and any defects 
which are discovered are to be made good, and the compart¬ 
ments re-filled and tested until found perfectly water-tight. 

CEMENT. 

A coating of cement or composition (principally composed 
of bitumen and Roman cement), as approved, is to be placed 
on the inside of the bottom and wherever else directed; to be 
of the necessary form and thickness, and no more, for carry¬ 
ing the water to the pumps. At the extremities of the vessel, 
and at other places where more than the ordinary bulk of 
cement is required, to be first given a thin coat of cement, and 
when this is dry to be filled with coke, and liquid cement is to 
be poured on repeatedly till the whole mass is solid and 
impervious to water. Care will be taken to have all plates, 
angles, &c., thoroughly cleaned before applying the cement. 
As far as practicable provision is to be made in building the 
[ vessel for rendering access to the different parts of the bottom, 
&c., as easy as possible, in order that the cement, &c., may be 
examined and repaired. 

GENERAL FASTENINGS, QUALITY OF MATERIALS AND 
WORKMANSHIP. 

All rivets are to be of steel, and must satisfy the priuted 
' code of tests supplied with this specification; those not less 
than inch in diameter to be made of a conical form under 
the head. 

The breadth of the edge-strips, laps, and butt-straps, where 
not specified, and the size, form, and pitch of the rivets, to be 
as may be directed by the superintending constructor. 

10 . [ 2240 ]

The riveting is to be executed in a careful and workman¬ 
like manner, the rivets thoroughly fitting the holes, and the 
greatest care is to be taken in punching to prevent unfair 
holes; all such holes are to be rimmed out before riveting, 
and a rivet suitable to the increased size of hole to be inserted. 
The counter-sinking is also to be carefully done. All rivets 
to be laid up, and all rivet-work to be completed in the man¬ 
ner required. The inspector may require any holes to be 
drilled and bolts turned for them, or he may substitute bolts 
for rivets, or make other changes of this kind, whenever he 
may think desirable, without additional charge. 

The whole of the remaining bolts and screw-fastenings 
throughout the ship are to be of the very best materials and 
workmanship; to have copper or brass metal-fastenings in the 
internal and other fittings, where usual in the U. S. Navy.

TESTS OF STEEL FOR CRUISERS 


INSTRUCTIONS TO INSPECTORS. 


The following rules are prescribed in order to insure the fulfillment 
of the clause of the act of Congress of August 5th, 1882: u Such ves¬ 
sels * * * * to be constructed of steel of domestic manufacture, 

having as near as may be a tensile strength of not less than sixty 
thousand pounds to the square inch, and a ductility in eight inches of 
not less than twenty-five per centum.” 

I. All ship-plates, beams, angles, rivets, bolts, boiler-plates, and 
stays to be inspected and tested at the place of manufacture by a naval 
inspector of material, and to be passed by him, subject to restrictions 
hereinafter mentioned, before acceptance by the ship-builders, whether 
Government or private, for incorporation into said vessels. 

II. Every plate, beam, and angle, supplied for these vessels, to be 
clearly and indelibly stamped in two places, and with two separate 
brands: 1st, with that of the maker, which shall distinguish the name 
of the manufactory or company. 2d, with the regulation brand of the 
naval inspector of material. The latter not to be stamped upon any 
of the above-named material until it shall have passed an inspection 
for surface or other defects of manufacture and physical tests, and 
have been accepted by the inspector, and have been stamped with the 
maker’s brand. 

In case of small articles passed in bulk, the above-mentioned brands 
shall be applied to the boxing or packing-material of the objects. 

No steel material to be received at the building-yards for incorpora¬ 
tion into vessels except it bear, either upon its surface or that of its 
packing, both of these brands, as evidence that it has passed the neces¬ 
sary Government inspection. 

III. The weights of all plates, beams, angles, &c., must be obtained 
by the inspector of material before delivery. 

Plates of 12| pounds per square foot or less, and strips and bars of 
6 pounds per lineal foot or less, may be accepted if the weights vary 
between 3 per cent, above and 5 per cent, below the specified weights. 












78 


ANGLES, BEAMS, T-BARS, ETC. 

V.—Angle-bars are to be subjected to the following additional tests: 
A piece cut from one bar in twenty to be opened out flat while cold 
under the hammer; a piece cut from another bar in the same lot shall 
be closed until the two sides touch while cold. 

Bulb and T-bars are to be submitted to a closing test similar to that 
prescribed for angle-bars. 

Bars submitted to these tests must show neither cracks, clifts, nor 

flaws. 

RIVETS. 

Each 1,000 pounds of rivets from the same heat of metal shall con¬ 
stitute a lot and be accompanied by two sample bars, each 18 inches 
long, for tensile test. These samples for tensile test shall be cut from 
the bars from which the lot of rivets is made, and be stamped with a 
number which shall also be placed on each box or package of that lot. 

These samples to be subject to the same tensile test as that required 
for the plates. 

The lot of rivets from which this sample bar does not fulfill the re¬ 
quirements of tensile strength and elongation required for plates is 
to be rejected. 

From each lot six rivets are to be taken at random and submitted 
to the following tests, two rivets to be used for each test: 

1st. Two rivets to be flattened out cold under the hammer to a 
thickness of one-half the diameter without showing cracks or flaws. 

2d. Two rivets to be flattened out hot under the hammer to a thick¬ 
ness one-third the diameter without showing cracks or flaws. 

3d. Two rivets to be bent cold into the form of a hook with parallel 
sides without showing cracks or flaws. 

The acceptance of material under these tests will not relieve the 
contractor from the necessity of making good any material which fails 
iu working or may be rejected by the inspector.
